When two waves of aimost equal frequenies `n_(1)` and `n_(2)` are produced simultaneously, then the time interval between successive mixima is

A

`1/(n_(1)-n_(2))`

B

`1/n_(1)-1/n_(2)`

C

`1/n_(1)+1/n_(2)`

D

`1/(n_(1)+n_(2))`

Text Solution

Verified by Experts

The correct Answer is:
A

Number of beats per second `=n_(1)-n_(2)`
`therefore` Time interval between two succsesive maxima `=1/(n_(1)-n_(2))`
